   Earth microbes survive in simulated Saturn moon Enceladus ocean

   Scientists have found that Earth microbes can survive in conditions similar to those of Saturn's moon Enceladus. In laboratory experiments, microbes from deep-sea hydrothermal vents off Japan thrived in a high-pH brine mimicking Enceladus's subsurface ocean. This discovery suggests that life could potentially exist on Enceladus, making it a more promising target in the search for extraterrestrial life.

   Why it matters

   Enceladus, a moon of Saturn, has a subsurface ocean beneath its icy crust, which is believed to have conditions suitable for life. The moon's ocean is thought to have a high pH level and contains various organic compounds. Previous studies have suggested that Enceladus could support life, but this new research provides further evidence of its potential habitability.

   What is confirmed

   • Earth microbes can survive in a high-pH laboratory brine mimicking the subsurface ocean of Saturn's moon Enceladus.
   • The microbes used in the experiment were from deep-sea hydrothermal vents off Japan.
   • The experiment suggests that life could potentially exist on Enceladus.
   • Enceladus's subsurface ocean is believed to have conditions suitable for life, including a high pH level and various organic compounds.

   Still unconfirmed

   • Detecting signs of life on Enceladus may be easier than expected.

   What to watch next

   • Future missions to Enceladus to search for biosignatures
   • Further laboratory experiments to simulate Enceladus's ocean conditions
   • Analysis of data from the Cassini mission to Saturn
